New York attorney general challenges CFTC order shielding Kalshi

New York Attorney General Letitia James has asked a federal court to disregard a CFTC emergency order that would effectively place Kalshi's operations beyond state reach — a direct challenge to the federal preemption argument that has, until now, been winning.

The CFTC order is the same instrument that stopped Arizona cold in May. When U.S. District Judge Michael Liburdi ruled that Kalshi operates as a designated contract market under federal oversight, Arizona's 20-count criminal case in Maricopa County Superior Court died on the vine. The federal government then sued Arizona, Connecticut, and Illinois directly, making explicit what the preemption argument implied: Washington intends to hold this line.

New York is testing whether that line holds in the Second Circuit, which is not the Ninth Circuit and has no obligation to follow Friday's Nevada ruling.

That ruling matters here, but not cleanly. The Ninth Circuit found that the Commodity Exchange Act does not stop Nevada from applying its gambling statutes to Kalshi's sports-event contracts. Arizona Attorney General Kris Mayes called this a vindication of state authority. In a narrow technical sense, she is right. In a strategic sense, she is describing half the picture. The Ninth Circuit simultaneously sent the election-wagering question back to the district court — which means the harder case, the one Mayes actually filed in Maricopa County, is unresolved. Sports contracts and election contracts are being treated as separate questions, and the sports ruling does not carry the election answer with it.

New York appears to be pressing exactly that seam. The CFTC emergency order is not a court judgment. It is an administrative instrument, and James is arguing that a federal court should not give it dispositive weight. If she is right, the preemption shield that stopped Arizona becomes considerably thinner in jurisdictions where federal judges are more skeptical of agency authority — and post-Chevron, that skepticism is structurally higher than it was five years ago.

I have watched federal preemption arguments used as a first-mover advantage before. They work until they encounter a court that reads the statutory text differently, and then they fail everywhere simultaneously. The CFTC's position rests on Kalshi's designated contract market status — a classification built for commodity derivatives, now being stretched to cover contracts on who wins a Senate seat. That stretch is what New York is pulling on.

The consensus reading of this week's events is that Kalshi won on sports and faces a slower fight on elections. The Polymarket fundraise and the volume numbers have kept attention on growth. But the New York filing is the development that will matter longer, because it puts the CFTC emergency order itself in front of a judge who did not issue it and is being asked to treat it as binding. Whether that judge agrees will determine whether federal preemption is a wall or a door that some states can walk through.
